I did not say he needs a 750 Demon.. your putting words in my post.

My reasoning is that the 600 will definitely be under-carbed with the Vortec Heads.. and the air-gap Intake.. The Demon is basically a more Adjustable Holley, which in my experience makes it a better Carb.
He said "better power/mileage/low end torque.." The Demon 650-750 will do 2 out of those Three, better than a Holley or an Edelbrock...
And to tell you the truth, He should give the engine what it wants, Not what we want him to get!

The original question was which of the two carburetors he currently owns would work better for his truck and not what would be the best carb to buy.

The original question set aside my truck is very similar to his engine wise but with a manual trans and I have put on four different carbs that I have (750 vac sec Demon, 1850 Holley, 1406 Edelbrock & rebuilt stock Q-Jet). The 600 was by far the best for a street driven truck but I went with the 1406 because it had an electric choke and the Holley had no choke at all. The 750 was just too much for a 5400 pound 4x4 truck in city driving.

In a light car with that engine a 750 would work great but on the street in a heavy truck the 1850 Holley is much better and he made the right choice. It may be short on top end power but makes up for it with throttle response and drivability. Just because it makes the most power doesn't mean it is the best for the application.
